We focus on the application of polarimetric approaches for the characterization and the modelling of liquid crystal spatial light modulators, since they can fully exploit the inherent birefringent properties of such devices. In this work we cover the full breadth of possibilities: from the basic understanding of the 3D liquid crystal alignment, via rigorous numerical simulations, to the precise radiometric and polarimetric measurements of periodic structures, the 2D mapping of the properties for polarization and phase applications, and to the generation of polarized structured beams. Theory, experiment and simulation are combined consistently.

摘要

We focus on the application of polarimetric approaches for the characterization and the modelling of liquid crystal spatial light modulators, since they can fully exploit the inherent birefringent properties of such devices.
